In life, I often hear people say that the jadeite is true and which one is fake. Why do they say that it is true, and that it is false and false, what is the criterion for judging whether it is true or false?
1. True jade: It should be a naturally occurring jadeite, subject to the following conditions:
(1) Its mineral composition is mainly a collection of natural jadeite and sodium pyroxene. The chemical composition of jadeite is NaAlSi2O6. It may also contain Fe and Cr.
(2) Its color is naturally formed.
(3) Its structure and structure maintain its natural state.
(4) No external substances are added.
2. Fake jade: – posing as a product.
Its appearance color and transparency may be very similar to jade, but its material composition is not jadeite and sodium pyroxene, it may be other natural minerals, such as dyed quartzite, green chalcedony...etc.
3. Partial fake jade - artificial treatment of jade:
Its mineral composition is a collection of natural jadeite, that is to say, its jade itself is true (natural), but its color structure is treated differently by humans and can be divided into:
(1) Dyeing jade: Jade has the same physical properties as natural jade, but the color is not formed naturally, but is formed by artificial dyeing. This jadeite is called C goods.
(2) Jadeite filled with resin after pickling: natural jade, degreased with strong acid and then filled with resin. The jade itself is a natural jade, retaining the original color, removing the secondary color, and the structure is damaged. The addition of the resin increases its transparency. It looks very beautiful when it looks rough, because the color is bright, and when it is carefully observed, it shows a waxy luster. This jadeite is called B goods.
(3) Film wrapped jade: natural colorless or light-colored jade, wrapped with fresh green plastic film on the outside, showing a bright green color, the green surface is purely illusory.
(4) Mezzanine jade: natural colorless or light-colored jade with good transparency. In order to fake false colors, divide the light body ring face into two halves along the curved surface, then sandwich the fresh green plastic in the middle to make the jade ring The surface is bright green.
